CENTER-BEARING.

SPECIFICATION forming part of Letters Patent N 0. 715,085, datedDecember 2, 1902. Application filed January 2, 1902. Serial No. 88,161.(No model.)

T0 ctZZ whom it may concern:

Be it known that LGEORGE I. KING,a citizen of the United States,residing at Middletown, Pennsylvania, have invented a certain new anduseful Improvement in Center-Bearings, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich Figure 1 is a top plan view of my improved center-bearing. Fig. 2is an elevational view of the same. Fig. 3 is an elevational view,partly in section, with a bolster in position. Fig. 4: is a verticalsectional view of a modified form of center-bearing, and Fig. 5 is adetail View of the king-pin.

This invention relates to a new and useful improvement incenter-bearings for railroadcars, the object being to construct abearing of the character described for use particularly in connectionwith the body bolster or transom of the car and to locate the head ofthe king-pin below the plane of the upper face of the bearing, wherebythe bearing can be attached to and used in connection with continuousbody-bolsters (which extend from side to side of the car) withoutnecessitating the removal of any portion of the bolster to accommodatethe king-pin.

This invention consists in the construction, arrangement, andcombination of the several parts, all as will hereinafter be describedand afterward pointed out in the claims.

In the drawings, 1 indicates the body-bolster, which is here shown asbeing I-snaped in section, to which bolster my improved center-bearingis attached. This center-bearing is preferably made in the form of amalleable or steel casting and is provided with an outwardly-extendingattaching-flange at its upper portion, through which pass the securingbolts or rivets.

2 indicates the walls of the center-bearing, which are reinforced andstrengthened by externally-arranged Webs 3.

4. indicates a hollow boss axially arranged with respect to thecenter-bearing, said boss aifording a seat for the king-pin. This bossis strengthened by webs 5, which are practically in radial alinementwiththe webs 3. The walls 2 and 4 are formed with alined openings 7, throughwhich is designed to pass a locking-key 8, said key also passing throughan opening in the king-pin and supporting the same in position.

In operation the center-bearing is bolted or riveted to thebody-transom, and the kingpin 9, being provided with an opening in itsupper end, as shown in Fig. 5, is introduced into the boss in thecenter-bearing and rotated until its opening 10 registers with thealined openings 7,when the cross-key referred tois introduced intoposition, said cross-key being held against displacement by the use ofrings, which are sprung into position through openings in its ends, orcotter-pins, as is Well understood.

In Fig. 4 I have shown a modified form in which the central bossterminates below the plane of the upper face of the bearing, whereby theking-pin (indicated at 11 and provided with the head 12) may be used. Inthis instance the center-bearing should be bolted in position, so thatit can be readily detached. The king-pin in this form is introduced fromabove, and when the bearing is secured to the bolster the bolsterprevents the pin from rising to any considerable extent.

In both forms of my invention it will be noted that the king-pin is heldfirmly in position in the center-bearing and that the bodybolster is notmutilated by being cut away to receive the upper end of the king-pin,that the king-pin may be readily and quickly removed andinserted in theconstruction shown in Figs. 1 and 2, while in Fig. 4 the centerbearingcan be readily and quickly detached by unscrewing the nuts on thesecuring-bolts.

I am aware that many minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

ICO

1. A center-bearin g for ears independent of and adapted to be securedto the under side of abody-bolster, said bearing having means engagingtherewith and with a king-pin for holding said king-pin in position;substantially as described.

2. A center-bearing for cars independent of and adapted to be secured tothe under side of a body-bolster, said bearing consisting of a bodyportion and-an axial boss, a king-pin and means for engaging said bossand said pin for holding the pin in position; substantially asdescribed.

3. A center-bearing for cars comprising a body portion having an axialboss for receiving the upper end of the king-pin, radial Webs betweensaid body portion and axial boss, said king-pin terminating below theplane of the upper face of the center-bearing, and means forlocking saidking-pin in position; substantially as described.

4. The combination with outer wall and a center-bearing provided with anaxial boss, of strengthening-webs therefor, walls at the outer ends ofsaid webs, and a king-pin Whose upper end terminates below the plane ofthe upper face of the center-bearing, and means passing through theouter wall and axial boss for securing said pin in position;substantially as described. 7

5. The combination with a center-bearing adapted to be secured to theunder side of a body-bolster, comprising a body portion and an axialboss, reinforcing-webs for said parts, and alined openings for said bodyportion and boss, of a king-pin provided'with an open- .ing in its upperend designed to register with said alined openings, a cross-key passingthrough said openings and means for locking said cross-key in position;substantially as described.

6. The combination with a body-bolster, of a center-bearing securedthereto and being provided with an outer wall, a central boss, anopening in its lower face for the reception of the king-pin, a king-pinarranged in said opening, its upper end terminating below thebody-bolster, and means for securing said king-pin to saidcenter-bearing; substantially as described.

7. The combination with a body-bolster, of a center-bearing securedthereto and provided with an opening in its lower face, a king-pinarranged in said opening, a key passing through said center-bearing andsaid kingpin for holding said king-pin in position, and means forpreventing the displacement of said key; substantially as described.

8. The combination with a center-bearing comprising a body portion andaxial boss provided with alined openings, perforated lateral flangesprojecting from said body portion adapted for securing the bearing tothe under side of a body-bolster, of a king-pin provided with an openingdesigned to register with said alined openings, and a cross key passingthrough said openings adapted to lock said king pin in position;substantially as described.

9. The combination with a center-bearing comprising a body portion andaxial boss provided with alined openings, perforatedlateral flangesprojecting from said body portion adapted for securing the bearing tothe under side of a body-bolster, of a king-pin provided with an openingdesigned to register with said alined openings, and registering meansfor securing said king-pin within said center-bearing; substantially asdescribed.

10. The combination with a center-bearing comprising a casting formedindependently of the body-bolster and adapted to be secured thereto,said casting having a body portion and axial boss provided with alinedopenings, of reinforcing-webs between said parts,

a king-pin provided with an opening designed to register with saidalined openings, and a cross key passing through said openings adaptedto lock said king-pin in position; substantially as described.

11. The combination with a center-bearing comprising a casting formedindependently of ;the body-bolster and adapted to be secured thereto,said casting having a body portion and axial boss provided with alinedopenings, of a king-pin provided with an opening designed to registerwith said alined openings,

a cross-key passing through said coincident openings, and means forsecuring said key in position; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence oftwo witnesses, this 19th day of December, 1901.
